Titanium tubesyog dav siv nyob rau hauv ntau yam lag luam vim lawv cov khoom zoo heev. Txawm li cas los xij, lub xub ntiag ntawm vanadium impurities, feem ntau VOCl3 thiab ib qho me me ntawm VCl4, tuaj yeem ua rau TC4 titanium alloy raj tuaj yeem pom cov xim daj. Cov txheej txheem refining lub hom phiaj tsis yog tsuas yog tshem tawm cov xim tsis zoo xwb tab sis kuj tshem tawm cov pa oxygen, ua rau nws yog ib qho tseem ceeb hauv kev ua kom tiav high-purity titanium raj.
Kev Sib Tw ntawm Vanadium Impurities
Vanadium impurities nyob rau hauv titanium raj tsim teeb meem vim lawv cov ntsiab lus boiling zoo sib xws thiab cov txheeb ze volatilities. Piv txwv li, qhov sib txawv ntawm qhov sib txawv ntawm cov titanium raj thiab VOCl3 tsuas yog 10 degree, nrog rau qhov sib txawv ntawm d=1.22. Ib yam li ntawd, qhov kub ntawm qhov sib txawv ntawm TC4 titanium alloy raj thiab VCl4 yog 14 degrees Celsius. Thaum lub cev txoj kev, xws li high-efficiency distillation yees, theoretically muab ib tug txhais tau tias kom tshem tawm vanadium impurities yam tsis muaj tshuaj reagents, lawv tsis tau muaj kev lag luam vim yog siv zog tseem ceeb, cov cuab yeej siv siab, thiab cov teeb meem tsis daws teeb meem nrog cov hlab ntsha siab.
Refining Methods
Muab cov kev txwv ntawm kev siv lub cev, kev siv tshuaj lom neeg feem ntau yog siv rau kev tshem tawm vanadium. Tshuaj refining yuav qhia cov reagents tshwj xeeb rau hauv titanium raj los xaiv los yog precipitate VOCl3 (los yog VCl4) impurities, uas ua rau insoluble aluminate tebchaw. Qhov kev sib cais no tso cai rau kev sib cais ntawm vanadium impurities los ntawm TC4 titanium alloy raj. Xwb, xaiv adsorption ntawm VOCl3 (los yog VCl4) tuaj yeem ua tiav, sib cais vanadium impurities los ntawm titanium alloy raj. Lwm txoj hauv kev suav nrog kev xaiv VOCl2, txhawb kev sib cais ntawm alumina impurities los ntawm TC4 alloy.
Kev xav yav tom ntej
Thaum cov txheej txheem rau kev tshem tawm vanadium hauv kev ua kom zoo ntawm TC4 titanium alloy raj muaj nyob, cov txheej txheem zoo tshaj plaws uas tau txais txiaj ntsig zoo, ua haujlwm tsis tu ncua, thiab siv tau yooj yim tseem yuav tsim. Kev tshawb fawb yav tom ntej yuav tsum tau tsim cov txheej txheem tsim khoom zoo uas suav nrog kev yooj yim, tus nqi qis, kev ua haujlwm zoo, thiab kev ua haujlwm tas mus li.
Lub xub ntiag ntawm vanadium impurities nyob rau hauv titanium raj nthuav tawm cov kev cov nyom, cuam tshuam rau ob qho tib si xim thiab kev ua haujlwm ntawm TC4 titanium alloy raj. Cov txheej txheem refining plays lub luag haujlwm tseem ceeb hauv kev tshem tawm cov impurities los txhim kho cov purity thiab zoo ntawm titanium raj. Thaum lub cev txoj kev muaj peev xwm theoretical, cov tshuaj lom neeg tam sim no muab cov txiaj ntsig zoo ntawm kev tshem tawm vanadium. Txawm li cas los xij, kev tshawb fawb ntxiv yog xav tau los tsim cov txheej txheem kev tsim khoom ua kom zoo dua qub uas ua tau raws li cov txheej txheem ntawm kev siv nyiaj txiag, kev ua haujlwm tsis tu ncua, thiab kev siv yooj yim. Los ntawm kev hais daws cov teeb meem no, kev lag luam titanium tuaj yeem ua kom muaj cov khoom zoo titanium raj rau ntau hom kev siv.
